EXPANSION PIPE-JOINT.

Application filed Jane 21, 1919.

I l I .l 0 all who-21L it may con/rem e it known that I, Fmznmnca C. limo MAX, a citizen of Holland, who has declared intention to become a citizen of the United States, residing at Martinez. in the county of (ontr (.osta, State of California. have invented new and useful Expansion Pipe Joints, of which the following is a specification, in such full and clear terms as will enahle those skilled in the art to construct and use the same.

This invention relates to an expansion joint for pi )es and one of its objects is to produce a nigh pressure expansion joint which will not only allow the pipe to move longitudinally hut will also permit a certain amount of lateral movement as well without injury thereto.

Another object of the invention is to produce a connection which will be capable of preventing the pipe joints from telescoping ovcr each other and which will he provided with means to prevent the pipes from drawing out of the inclosing sleeve.

Other ohjeets of the invention will. appear as the description proceeds.

An emhodiment of the invention is shown in the drawings in which the same reference nui'neral is applied to the same portion throughout,-lnrt I am aware that there may he modifications thereof.

Figure 1 is a side elevation of the complete expansion joint,

Fig. 2 is a vertical sectional view of the same, and 4 Fig. 3 is an end view.

The joint comprises two main slhevr's 1 and 2. each ol which has flanges at its ends as indicated at 3 to 6 inclusive.

'lhcse sleeves are secured together by means of the holts 7 which pass through the flanges 4 and :7 and a plate 8 is secured he tween the two sleeves against which the pipes ahut should they move toward each other.

,Thc oulcr cud ol' the sleeves is chamhcrcd out to rcccivc the packing [0. ll llirougli whi h the pipc.- l2 and l-i pass. liar-h pipe has a llangc. scc l4.

packing are held in place hy means of the flanged gland rings in and 20; holts 2i heing used for this purpose. i

The sleeves 1 and 2 are each provided with an interior llange as shown at 22 and 23 and it will he noted that the rings 18 do not touch lhe sleeves l and 2, while the rings 19 and 20 do not touch the pipe; so that there is a possihility of considerable lateral movement of the two pipcs in the sleeves.

Should the p nes pull away from each other, the flanges n; and 17 will prevent them from pulling out of the sleeves, and if they move toward each other, the plate H will prevent them from telescoping one over the other.

It .will he understood that the sleeves l and 2 touch the pipes 12 and 13 in one plane only, while the .qlands l9 and 20 do not touch them and as the rings in and packing rings 10 and 11 are more or less llexihly connected with the two sleeves the pipes have considerable lateral movement without injury to the sleeves. The only place the sleeves l and 2 touch the pipes is at the inwardly projecting flanges 22.

What I claim is as follows. hut various modifications may he made in the construclion shown in the drawings'and above particularly described form, within the purview ol" my invention.

I claim:

I. An expansion joint for pipes comprisin; a: pair of flanged sleeves for holding two pipes together, a flange on each pipe. to prevent them from hein, drawn out of the slccvcs, an inwardly projecting flange carricd by each sleeve, each contacting with the pipes in a single plane and packing for the pipes which will permit lateral luowiucnt of said pipes with respect to the sleeve.

2. An expansion joint for pipes comprising a pair ol' flanged sleeves for connecting two pipes, means to connect the two sleeves together through their llangcs. a plate lictwccn the sleeves l'or precluding the pipes fl'Ulll tclcscoping and a llangc on cach pi no lo prcvcnl. lhc pipes from pulling out oll ic' sleeves.
